Answer 3

Calculation of Remaining Text Pages

To calculate the remaining pages of text, we can use the information provided. On the first day, the operator typed 3/5 of the text, and on the second day, the operator typed 1/4 of the total text.

Let's calculate the remaining text pages:

Step 1: Calculate the total text typed by the operator. - On the first day: 3/5 of the text - On the second day: 1/4 of the text

Step 2: Subtract the total text typed from the original total to find the remaining text.

Calculation: - Let's assume the total text is represented by T pages. - Total text typed on the first day = (3/5) * T - Total text typed on the second day = (1/4) * T - Total text typed = (3/5) * T + (1/4) * T - Remaining text = T - [(3/5) * T + (1/4) * T]

Step 3: Simplify the expression to find the remaining text.

Calculation: - Remaining text = T - [(3/5) * T + (1/4) * T] - Remaining text = T - [(12/20) * T + (5/20) * T] - Remaining text = T - [(17/20) * T] - Remaining text = (20/20) * T - (17/20) * T - Remaining text = (3/20) * T

Therefore, the remaining text is 3/20 of the total text.

This calculation assumes that the operator types a consistent amount of text each day. If the total text is known, we can use the above calculation to find the remaining text.
